It seems everyone who is having client crashes has picked Unholy. That means it's either something about the base, or something about the class (perhaps body value).
There are a lot of unholy players who don't crash, so it's not a directly that easy to reproduce.
I'll take a look at the base, but it would be helpful if someone who crashes on Unholy could try to get into the base on a non-unholy character, and see if they still crash.
